To all whom it may concern:

Be it known that I, HARRY C. BUnoUP,"a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Trucks; and I do hereby declare the followingto lbe a full, clear, and exact descri tion of the invention, liers skilled in the art to which it appertains to make and use the same.

My invention relates to the construction of'trucks for railway cars and has .for its principal objects to strengthen, cheapen. and simplify the construction of the truck side frames, andto render possible the ready connection of the bolster and side frames inJ a sim le manner.

enerally stated, my invention may be said to reside in a car truck upon the side umn Guides which may be separated to permit tIie introduction cfa bolster between them, and which may be afterwards moved towards each other to engage the bolster-' guides of the bolster, to thereby connect In the drawings chosen for the purpose of illustrating my invention, the scope whereof is pointed out in the claims, Figure 1 is a view, partly in side elevation and partly in centra section, showing a c'ar truck embod ing my invention Fig. 2 is a plan View of t 'ie central portion. of the truck shown in Fig. 1; Fig. 3 is a section on the line 3m3, Fig. l, the bolster, however. being illustrated in plan; Fig. Lis a vertical transverse/ section taken on the line i-,fi/Fig.l lfshowing the relation of the side-frame column to one of the adjustable column-guides; Fig. 5 is a detail ierspective View of one of the adjustable column-guides shown in the preceding figures of the drawings Fig. 6 isa view, partly in side elevation and partly in central section, showing a car truck embodying my invention in a modified form g Fig. A7 is a plan view of the central portion of the truck` shown in Fig. G; Fig. 8 is a section on the line 8-8, Fig. 6, the bolster being shown in plan.; Fig. 9 is a vertical transverse'scotion on the line 9--9, Fig. 6; Fig. 10 is a vertical transverse section taken on the line 10410, Fig. 6; Fig. 11. is view of a car truck, partly in side elevation and partly in central section, showing a furthcrmodiiication of my invention, the bolster-springs being omitted;

showing the relation of the side frame to on of the adjustable column guides.

1 Like' symbols refer to like parts wherever they occur.

I will now proceed to describe my inven- 'tion more fully, so that others skilled in the art to which it appertains may apply the same.k

In the drawings,

illustrated uwherein journal-box bolts 4 con- 75 iine the journal-boxes between upper and lower horizontally extending jaws formed integral with the side-frame 1.

In Figs. 6 and 11 the lower journal-box jaw 5 is omitted from the side-frame, the 80 journal-box being secured to said side-frame by means of a yoke 6 which extends' lbeneath the j ournal-box and along the outer side thereof, as will be readily understood..

The form of the truck bolster 2is alsoim- 85 material, saving only that it be provided with bolster-guides which are adapted to cooperate with the adjustable column-guides to form an interlocking connection ywhich l 'is the truck side frame, j I 2 the bolster and 3 the journal-boxes. The 70 shall permitvertical movement of the bolster with respect to the side-frames. In the particular applications of my invention illus'- trated in the drawings, a form of bolsterguide 7 which is in common use is employed.

tach of the truck side frames 1, which may be 'of cast steel, is preferably formed with a continuous top chord 8 and a continuous bottom chord 9, it being desirable to fashion such. chords as flanged members in order to im art stiffness to the side-frames 1005 without un uly increasing their weight. At

its center thelower chord of each sideframe is preferably provided with an integrally attached spring-seat 10 which forms a support Extending between the upper and lower chords, 8 and 9, respectivel of the side frame, and preferably integrally united with both, are columns 12 which guide and support the adjustable column-guides 13 carried ,110

in Figs. 6 to 10,-n1clus1ve,the columns 12 l "of Vthe side-frame.y also diverge, as in the conv struction just described, but the columnorder to guides 13 are formed in two parts, a wedge portion 16 and a shoe 17 having guide iianges 1S between which the columns 12 pass.

ermit the shoesv 1 7 to se arate so that the olster 2 mayl beinserte between them, the followingconstruction is provided.

The columns 12 are slotted lon their opposing faces to permit the passage of lugs 19-which are formed on the rear faces ofthe wedges 16 near the bottom thereof, andat the base of cach slot each ofthe several Ycolumns '12.is provided with a lug 20 having threaded enl gagement with a screw rod 21 the upper end of which bears u on the under side o the lug 19 formed upon t e adjacent wedge member 16. Openings are formed in the top lchord 8 directlv over the Wedges 16 in order to permit the' latter to be freely raised by the screw-rod .21, and in order to limit the downward movement of the shoes 17 the lateral facesof each column 12 are provided with stops 22 which engage the respective guide flanges 18 of said :shoes when the several parts are assembled. When' it 1s desired to assemblethe truck, the

wedges 16 are elevated by the screw-rods 21,'

the shoes 17 are lseparated, the bolstersprings 11 and bolster 2 are inserted, the shoes 17 are moved into engagement with their res ective bolster-guides 7, andthe screw-ro s 21' are then turned to permit the wedges 16 to assume positions 1n which they When the truck is to be assembled,

firmly support said shoes I against lateral se aration.

Figs. 11 to 13inclusive, I have'shown a construction embod mg some of the features of my invention. this construction the column-guides 13, whlchare of general tee form,"'are mounted u on vertically disposed columns "12, said co umns being provided with pockets orv recesses which permit the said column-guides to be moved toward and from each other. For the purpose of maintaining the column-guides 13 in engagement with the bolster-guides 7, keys, such a's A23, may be employed. These keys, which arel inserted through apertures formed in the top chord 8 ofthe side-frame, as will be readily` understood, may have a much greater taper than shown in the drawings, `if desired, or'

they may be ma'de of uniform cross-section throughout their length, 4in which case, of course, the corresponding faces of the columnguides 13 will be made vertical and keys of 'appropriate thickness will be employed to` maintainsaid column-guides in proper engagement with bolsters of dierent widths.

For the purpose of Jfurther strengthening the side frame show'l in Figs. 11, 12 and 13, a vertical web 24, which is cast integral with the'spring-sat 10 and columns 12, may be employed.. This web, it will be observed,

iorms a support for the column-guides 13,

which are rounded or beveled at their uptper inner corners so that they can be rea ily placed in position when brought over the por- 'tion of the web which is of least height.

Heretofore itvhas been impossible to conservice,"each different width of bolster necesstruct a single side-frame which could be used with the various widths of bolstersA 'm Width bolster opening; but side-frames constructed inj accordance with ymy invention are capable of being used with any of the many widths of bolsters.

While I have shown and described only one side-frame and its bolster connection, it

wl be understood that the other side ofthe.

truck is constructed in the same manner.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a car truck, the combination with a bolster, o'f sidefframes having column-guides which are ca, able of movement toward and from each ot er, and meansfor supporting said column-guides against lateral separation.

2. In a car truck, the combination with a bolster, of side-frames having columns, and column-guides mountedA on said columns, said column-guides being ad'ustablev inthe direction of length of the sai side-frames. l

iis

3. In a car truck, the combination with .a

bolster, of Aside-frames provided with col-r ed on some of said columns, thefcolumns of each side-frame being disposedl at anangle to each other. Y

4. In a car truck, the combination with a bolster7 of side frames provided with columns*7 the columns of each side-frame having their opposing faces disposed at an angle to each other, and column-guides mounted upon each of said side-frames, the column-guides on each side-frame being capable of move- -ment toward and from each other.

guides which are adjustable toward and from each other.

8. A car truck' side-frame having a bolster opening the sides of which are formed by col-l umns the opposing faces whereof are disposed atan angle to each other, said bolster opening being adapted to permit a bolster to project therethrough. e

9. A car truck side-frame provided with diverging columns forming an opening into and through which a bolster is' adapted to project. l

10. A car truck side-frame having columnguides provided with wedges whereby said column-guides may be adjusted toward and from each other. y

1l. A car truck side-frame having a oontinuous upper chord, a continuous lower chord, columns extending between. said chords, and adjustable column-guides car: 'ried by said columns.
